So I took my PCV off yesterday to check it out and try to clean it a little and I broke one of the clips that hold the lines on. Circled in red in this pic (not my car):

Any way to purchase just these clips? I'm guessing maybe not without buying the whole line assembly? And if not should I be worried? It seems to stay on pretty well because of the brackets holding the lines.
Also, what does the vent line with the green arrow do? I have an aftermarket intake and it doesn't fit snugly. Should I put a hose clamp or some RTV on it so it doesn't vibrate loose?
